Instead I suggest just using a freeform string ID. For practical reasons
we probably want to restrict this to regular characters, like we do
other ids (i.e. [-_A-Za-z0-9]). This allows

Hi,
This patch series adds a flag which allows pci devices being tagged
as not hotpluggable. It also sets this flag for a number of devices.
cheers,

This patch adds support for expiring passwords to vnc. It adds a new
vnc_display_pw_expire() function which specifies the time when the
password will expire.

no, problems exist with smaller amounts of RAM. with 16GB guest it is
trivial to get 1s stalls, 64GB guest, 3-4s, with more memory, migration

This patch tags all vga cards as not hotpluggable. The qemu
standard vga will never ever be hotpluggable. For cirrus + vmware
it might be possible to get that work some day. Todays we can't
handle that for a number of reasons though.

No, it just split the main bitmap into three bitmaps. I'm suggesting

Instead of directly executing writes and fsyncs, queue them and execute them
asynchronously. What makes this interesting is that we can delay syncs and if
multiple syncs occur, we can merge them into one bdrv_flush.
A typical sequence in qcow2 (simple cluster allocation) looks like this:

block-queue itself looks more or less ready to me now, the rest is
possible bug fixes and addressing review comments. So please, give
the first three patches a good review, they are in their final version

I don't know how good this is.
For another implementation of USB-over-IP you could look at Sun's
work with the SunRay thin clients. I believe some of it may be in
the OpenUSB codebase. (They forked libusb to make it work the way
they wanted.) I don't know how good
